AGAS-SCRUBBER.

SPECIFICATION forming part of Letters Patent N o. 460,300, datedSeptember 29, 1891. Application filed March 14, 1891. Serial No.384,994. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAMS BLODGET, a citizen of the UnitedStates, and a resident of New York city, in the county and State of NewYork, have invented an Improved Gas-Scrubber, of which the following isa specification.

Myinvention relates to gas-scrubbers of the type known as hot-tardryscrubbers. The

scrubber and finally discharges into a suit-A able receptacle while thegas is conducted into a holder,

The object of my invention is to produce a cheap, simple, and efficientapparatus, which will thoroughly eliminate all tar from the gas by apurely mechanical process and without the use of any purifying material.

. The subject-matter claimed is hereinafter specified.

The accompanying drawings represent so much of my improved apparatus asis necessary to illustrate this sub j ect-matter. Unless otherwisespecified, the parts are of ordinary construction.

Figure l is a side elevation, partly in section, of the scrubber; andFig. 2, asimilar plan View. Figs. 3 and 4 are respectively perspectivedetail views of the solid and perforated diaphragms employed.

The arrows show the direction of movement of the tar and gas. arisingmain A to the dry scrubber, which it enters at the top and at oneend. This scrubber is shown as composed of a series of inclined troughsB B', ttc., live in number, resting one upon the other and connectedalternately at opposite ends by passages C C', dac. The bottom of thesetroughs is left unobstructed, so that the tar thrown down may flowcontinuously therethrough in a direct course; but the gas is caused topursue a much more devious course by means of a series of The gas passesthrough` transverse diaphragms or partitions D E. These diaphragins areshown as alternating in the troughs, Which are provided with closedapertures or hand-holes G at suitable intervals to afford access theretofor cleansing, &c. The diaphragms D are shown as constructed in the formof oblong plates secured to braces or cross-strips (Z in such manner asto leave a free space around all fouredges, around which the gas mayfiow after impinging against the plates. The alternate partitions E areshown as perforated or divided centrally and supported by braces e, andwith their upper and outer edges close to or against the top and sidesof the troughs, leaving' openings at the bottom for the flow of the tarand one at the center, through which the gas passes and iinpingesagainst the adjoining solid partition. The outer corners of these platesare shown as clipped diagonally, so as to leave spaces e. The gasentering the scrubber passes around the edges of the plate D, throughthe central opening in adjoining plate E, and, impinging against thenext solid plate D, is thrown laterally against the Walls of the trough,passing around the edges of the partition and through the centralaperture in the next partition. The impingement of the gas against thesurfaces and its friction thereon break up the globules of tar and thetar descends to the bottom of the trough, along which it flows. Thepurified gas and tar are finally taken off at F.

I claim as my invention 1. The combination, substantially ashereinbefore set forth, of a trough havingan inclined bottom, inlet andoutlet openings for the trough, and alternately solid and perforatedpartitions suspended in the trough and above the bottom thereof, thesolid partitions having spaces between their edges and the walls of thetrough, for the purpose specified.

2. The combination, substantially as hereinbefore set forth, of atrough, gas inlet and outlet openings therein, alternately solid andperforated partitions suspended in the trough above the bottom thereofto leave a free coutiuuous passage for the fiow of tarry matter, andgas-passages above and at the sides ot' the solid partitions and at thecenter of the perforated partitions.

3. The combination,substantially as hereinpartitions being arrangedabove the bottom Io before set forth, of a series of inclined troughs,of the trough, for the purpose specified.
